Sierra and Time Machine

Hi Don (@arizonadonn),

Did it help?

Just asking...

Jur Kuipers, The Netherlands.

I solved my slow-Time Machine problem in macOS Sierra!

After Time Machine (again) took ages to backup I stopped Time Machine by unchecking "Automatic backups" in System Preferences/Time Machine (unchecking the new little "check-box").

After this abrupt stop I again checked that little check-box "Automatic backups" in System Preferences/Time Machine.

Then activated "manual backup" (starting backup) by activating Time Machine via menubar.

The first Time Machine (TM) was slow again, but after stopping and restarting a few times (stop and restarting by check-uncheck/System Preferences and starting up by "manual backup"/menubar).

TM then copied as it should.

...But then after successful copying "Backup thinning" took forever... ("opschonen" in Dutch).

Stopped "Backup thinning" by unchecking Automatic backups" in System Preferences/Time Machine.

Then activated "manual backup" by activating Time Machine via menubar (after I again checked "Automatic backups" in System Preferences/Time Machine).

Now "Backup thinning" - when necessary - completes the TM-backup successfully.

TM is working fine (and fast) now (automatic hourly backups).

Perhaps this is helpful?

It worked for me.

Best regards,

I have upgraded to Sierra. Since then, the capsule stopped working as hard drive with my machine. It does not even show up in the finder. I have no problem to connect to it with an old mac. Something is going on

Hi Don,

I solved my problem (see above)...

Perhaps that helps...

I noticed that in Console (typing "backupd" in the search box/"diagnoses and user-info") many lines with "backupd" in it.

In never saw this in previous OS X-versions - see also this question/thread of mine...How can I see Time Machine activity in Console with macOS Sierra.

Could it be that after updating to Sierra Time Machine is indexing the whole Time Machine-disk and this is the reason it takes forever?

It would be helpful to know what Time Machine is doing all this time...

A few years ago "pondini", who is king in solving Time Machine-troubles, was very active in "Apple Support Communities". He even has his own website concerning Time Machine... http://pondini.org

He did not update his website for a few years now...

His troubleshooting was very helpful to me then...

Were are the multilevel-experts?

Wow!

That *****!

You're not the only one who has problems with TM since updating to Sierra.

😟

Again...

It would be nice to see (in Console) what TM is doing.

Anyone? - multilevel experts???

Succes Don!

reboot your Mac, - hold Command+R keys (till after the "boing-restart-sound" and you see the Apple-logo).

Wait for dialogue-box to appear.

Make sure your wifi is active, on the right above in menu-bar (it could be you need the password of your internet-modem)

Then install macOS Sierra again (you need to type in your Apple-ID with password).

This is the way you install on top of your existing macOS.

Sorry, -

...it seems you're stuck.

Hope you're not in a loop now...

You don't have an old TM-copy (recent date) to restore your whole iMac to the (old) previous state anymore?

Your profile states you're Mac was on Lion, - correct?.

It seems to me that upgrading from Lion to Sierra could be the problem.

If you had El Capitan (10.11) I don't understand why you only have the option to install Lion (10.07).

Succes Don.
